Session description:

Plantation forests allow the selection of tree species at the establishment phase to respond or target specific objectives e.g. profitable timber and pulp supply. Increasingly selection of plantation trees is also guided by objectives such as to increase the resilience of newly planted forests against threats and negative impacts emerging under a changing environment. –Traditionally forest manager referred to their experience based on past plantations and their learning from their successes or failures to establish new stands with particular species. In a context of global change, such historic knowledge might have reduced validity and possible better ways to gain knowledge of site - climate matching for plantation trees is needed. This extends beyond the establishment phase over the full rotation of plantations and the stand making it more challenging due to the longer rotations of some plantation species. Due to the longer timeframes the anticipation of and resilience towards risks (at least partly) associated with climate change, such as new pests and pathogens, as well as the changing climate itself on the physiological processes will be crucial. As foresters are becoming more and more aware of this issue, there is a need to develop decision support tools and improve knowledge of the real adaptive capacity of the recommended planting material for plantations. There are many ongoing initiatives all over the world ranging from knowledge compilation from existing stands and trials designing and deploying experimental infrastructures to monitor and anticipate climate change impacts on plantations and organising relevant information in an appropriate way to facilitate decisions on tree planting material for forest managers and regional authorities in charge of tree species choices regulations: (1) First results from REINFFORCE network of arboreta analysis, an estimate of the potential of adaptation of genetic material for plantations.
